Title: Semiconductor device
Inventor: YAMAGUCHI TAKASHI
IPC: H01L27/02
Filed: 1988-07-27
Abstract: PURPOSE:To reduce the resistance of a p-type semiconductor region as a whole, to eliminate a potential gradient in the p-type semiconductor region, to prevent effectively the generation of a parasitic thyristor and to make possible the improvement of the reliability of a semiconductor device by a method wherein a p<+> semiconductor region of a concentration higher than that of the p-type semiconductor region is continuously connected to the p-type semiconductor region on the outer side of the p-type semiconductor region. CONSTITUTION:An N-type epitaxial layer 13 constituting a power supply island is formed on the whole surface of an Si substrate 11, a p<+> semiconductor region 14a is formed in the layer 13 and moreover, a p-type semiconductor region 14b of an impurity concentration lower than that of the region 14a is formed on the inner side of the region 14a. As the region 14a having a resistance lower than that of the region 14b is positioned on the outer side of the region 14b, the generation of a potential gradient in the region 14b is suppressed, the interior of the region 14b is held substantially in the same potential, the P-N junction between the region 14b and an n-type semiconductor region 15 can not be forward-biased, the generation of a parasitic thyristor is prevented and the reliability of a semiconductor device is improved.

IPC: B23P19/06
Filed: 1980-12-29
Abstract: PURPOSE:To uniformly clamp a bolt by a method wherein a ring-shaped piston is provided in the groove made in a ring-shaped body and oil is supplied to the groove for  pulling a number of bolts in the direction of a pull-out in proportion to the looseness  of the bolts and for tightening nuts by the play produced by the pull-out. CONSTITUTION:A ring groove 4 is made in the upper surface of a ring body 2 and a  ring piston member 3 is engaged with the groove 4. A connecting member 5 is piled on  the member 3 and the member 5 provided with a through screw hole 6 in both upward  and downward directions is inserted into the body 2 with a gap provided between them. The bottom surface of a collar portion 8 in the upper end portion contacts the  upper surface of the member 3 directly or indirectly via a contact surface 9 bent in a  spherical shape. A ring tube 12 made of flexible material is installed at the bottom of  the groove 4 and an operating fluid is supplied to and discharged from the groove.  When two parts P1 and P2 are insufficiently tightened, the member 5 is moved toward  the pull-out direction by the tube 12 via the member 3, whereas the gap C works to  rotate a nut N through a window hole 10 and tightens the nut to attach it under pressure to the surface of a part P2. If this clamping appratus A is attached to a number  of bolts and supplied with liquid pressure of a pump P, the bolts are uniformly  tightened.

IPC: H01M4/08
Filed: 1984-09-07
Abstract: PURPOSE:To prevent any deformation of the cut surface of a positive body and prevent any bur from developing in the cut surface so as to prevent any internal short-circuit by making the positive body by applying a positive mixture to a core consisting of a punched metal and then irradiating a laser beam along a line to cut the core coated with the positive mixture into a belt-like form with a given width. CONSTITUTION:After a positive mixture principally composed of manganese dioxide is applied to a core 12 consisting of a punched metal or an expanded metal, a thin laser beam from a laser oscillator is irradiated along a given cut line to make a beltlike positive electrode 6 with a given width. Next, the positive electrode 6, a negative electrode 7 made of lithium and a separator 5 are rolled into a spiral form to make a generation element 2. After that, the generation element 2 is sealed in a case 1, thereby assembling a nonaqueous electrolyte battery. Because of the above structure, the cut surface of the positive electrode 6 is prevented from getting out of shape and no burs develop in the core 12. Accordingly, any internal short-circuit of the battery is prevented, thereby improving the yield of making the generation element 2.

Title: Manufacture of plate for lead acid battery
Inventor: MACHIYAMA YOSHIAKI
IPC: H01M4/62
Filed: 1993-07-29
Abstract: PURPOSE:To form a lead oxide corrosion layer of necessary enough thickness in an interface between active material paste and a lattice unit in a short aging time. CONSTITUTION:Active material paste, with which a lattice unit formed of a lead alloy containing antimony is charged, is used by adding 0.02 to 0.2wt.% alkali metal sulfate (Na2SO4) or alkali earth metal sulfate (MgSO4). Relative humidity of the atmosphere during aging is controlled to 80 to 90%. Forming a corrosion layer is advanced by a local battery mechanism with a primary crystal 1 and eutectic crystal 2 of the lead alloy serving as the electrode and with free water in the paste 3 serving as the electrolyte, but since conductivity is increased by increasing an ion in the electrolyte, corrosion is quickly advanced.

Title: Defect deciding method for ultrasonic flaw detection of seal weld zone of resistance welded tube
Inventor: SUGIE YOSHINORI
IPC: G01N29/04
Filed: 1988-07-26
Abstract: PURPOSE:To decide a defect in the seam weld zone of the resistance welded tube by using both a 1st set reference as an acceptance/rejection criterior determined by specifications and a 2nd set reference wherein a defective sample is cut from a pipe which emits a reflection echo in a right-left direction and a weld defect is set in combination. CONSTITUTION:Ultrasonic waves 2L and 2R are made incident opposite each other in a left and a right direction close to the outer peripheral surface of the seam weld zone of the resistance welded tube 1 and the 1st set reference R1 wherein there is a weld defect when even one of reflection echoes exceeds a specific level is provided. Further, the 2nd set reference R2 is set wherein a weld defect is decided when the reflection echoes in the left and right directions are generated at the same lengthwise position in the seam weld zone. The weld defect is present vertically from the surface of the resistance welded tube 1, so the reflection echoes of the ultrasonic waves 2L and 2R are nearly equal in level. A flaw 5 other than the weld defect is prevent slantingly, so the reflection echoes of the ultrasonic waves 2L and 2R are different in level. For the purpose, both the reference R1 and R2 are used in combination to make a high-accuracy decision.
